The non stop problems the last few months and versions have been ridiculous. Have the same issues clSetkernelArg (-48) on many Polaris rigs.
i don't have problem
AMD driver: 20.4.2-2
Miner: PH 5.1c
because it is windows update problem, Microsoft force update of AMD graphics drivers. The speedest solution is roll back driver in device manager and pause windows update until the new phoenix miner version will be released
